To (all whom it may concern:

Be it known that 1, MICHAEL Llr'mn, e citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Furnece Wells; and I do hereby declare the following to he a. full, clear, and exact description of the invention, such as will enehle others skilled in the art to which it epperteins to melee My presentinvention relates to furnace well structures and is in the ncture of e modification of orimprovement on the furnece well structure disclosed and claimed in my application Serial Number 575,737, filed of dots July 17, 1922, and which spplicm tion was executed oi date July 1%, 1922. Generally stated, the invention consists oi the novel construction, errengement and combinations of parts hereinafter dmcrilced end defined in the claims.

in the drawings, whichv illustrate coin-v merciel embodimen s of my invention, like characters indicate like parts throughout the severed views.

Referring to the drawings:

In this improved well, as in'the well of my. eerller application, the complete well structure illustrated is mede up of whet may be designated es s rmenentouter wall end it repleceehle high refractory me sonry inner well.

Descrihin trsted in igs. 1 tot, inclusive, the nomerels l8 end 14: indicete, respectively, the lower and upper sections of chennel-sheped tile or masonry enchor horses in which the sections 13 serve es sill hloclrs end the sec tions 14;- serve as lintels. lln this strangement, the said blocks 13 end it ere epproxi metely ill-shaped in cross-section end their the infirst the construction illns' Vertical Webs are aligned o e set together to form the backs of the anchor boxes. lit

the arrangement at present heing considered, the end jointshetween the sill blocks 13 are horizontally oilset in respect to the end joints between the liniels 14 end piles tom ere placed on the intermediate portions of the former with the ends oi? the letter renting thereon. These pilesteis may he elforded by blocks of diderent form, but,

ill

preferably, ere made up of'lower hloclrs l5 and upper blocks 16. For e purpose which will more fully presentl appear, the sill hloclrs 13 are formed with raised ledges ll, end the under-surfaces of the lin-tels it are slightly inclined outwardly or toward the outer face or? the permsnent well structure. Consistent with this arrangement, the piles ter blocks 15. are formed with depressed ledges 18 that interlock with seid ledges ll and the upper loloclrs it? ere slightly teipered. so thet theyfit the inclined nndersnr laces of the lintels. Hence, when the wedge Elli shaped blocks 16 are iii-position, the blocks 15 will be positively interlocked with the sill blocks. Preferably, the above noted blocks 13, 14, 15 and 16 of the permanent outer wall are of high refractory material such as fire tile, but, in some instances, they might be made of less highly refractory matonal.

The replaceable inner wall should be made up entirely of high refractory blocks, bricks or tiles, and, as shown, it comprisesreplaceable horizontal belts of fire bricks 19 and, be-

ledges 21. To hold the inserted ends of the,

shelf-formin g blocks 20 interlocked tothe sill blocks, key blocks or bricks 22 are placed on top thereof and against the under-surfaces of the sill blocks. Saidkey blocks are preferably tapered or 'made' slightly wedgeshaped so as to better fit them for engagement with the inclined under-surfaces of the lintels 14. In most arrangements, the shelf-formingblocks 20 will be extended completely through the replaceable inner wall while the key blocks 22' will be extended only about one-half way through said replaceable wall and the spaces in horizontal line therewith are filled in by fire bricks 23 arranged to span the gaps between the groups of shelf-forming blocks. The spaces between the groups of shelf-forming blocks 20 are shown as filled in by fire bricks 24.

When the shelf-forming blocks are interlocked to the permanent outer wall, they afford shelves for supporting the horizontal belts 19of the replaceable fire bricks so that any portion of one belt ma .be removed without disturbing any portion of an adjacent belt. Also, the arrangement described permits all of the parts of the replaceable inner well, including the shelfforming blocks 20, to be replaced at will without disturbing the blocks or elements of the permanent outer wall. Advisably, space is left between the ends of the shelf-forming blocks 20 and the adjacent inner surfaces of the walls of the box-forming sills and lintels, so that in case said blocks 20 should become fused to the sill, they can be loosened by pounding on their exposed inner ends and driving the same slightly farther into the pockets of the boxes. Also, to provide for driving the key blocks 22 from working positions, the vertical walls of the lintels 14:

' further consider.

insane? are formed with holes 23 through which a punch or similar instrument may be inserted and drivenagainst said key blocks.

. The construction illustrated in Fig. 7 is like that already described in connection with Figs. 1 to 6, inclusive, except that the sill blocks 13, in this arrangement, are set with their joints vertically aligned with the cooperating overlying lintels and the .pilasters are interposed at these joints.

The construction illustrated in Figs. '8 and 9 is like that illustrated in Fig. 7 except that the sills 13'and lintels 14 are integrally formed or mounted as a single unit. Also, in Fig. 8, the channel-shaped boxes formed by the lintels 13 and 14' are shown as anchored to 'buckstays 24 by means of nut-equipped anchor bolts 25, such as illustrated in my prior application and not necessary for the purposes of this case to The modified construction illustrated in Fig. 10 involves certain of the principles of construction embodied in the construction are projected and arranged to support in ter osed belts of ordinary masonry 29, prefera ly of common brick. The said-elements 26, 27, 28 and 29 constitute parts of the socalled permanent outer wall. The sill blocks 26 and lintels 28 form channel-shaped anchor boxes that will be associated with interposed pilasters of suitable arrangement, such, for example, as illustrated in Figs. -2 and 7. The sill blocks 26 are formed with raised ledges 30. that interlock with depressed ledges 31 of replaceable shelf-forming blocks 32, which latter, like the blocks. 20, constitute elements of the replaceable inner wall. The numeral 33 indicates key blocks interposed between the shelf-forming blocks 32 and the undersurfaces of the overlying lintels 28. The depending webs or walls of the lintels 28 are preferably provided with punch holes 34 for facilitating the driving out of the key blocks 33. In this form of the wall, both the shelf-forming blocks 32 and the key blocks 33 are made wedge-shaped or flaring toward the inner surface of theinner Wall and the main body portion of the inner wall is of monolithic or molded structure 35 of fire clay or similar substance capable of being molded or cast to form and which, when hardened, will have a highly insane?" refractory character. In this arrangement, the wedge-shaped elements32 and 33 afi'ord dove-tailed anchors anchored to the outer wall and to the inner wall and securely holding the two together.

What I claim is:

1. A wall structure made up of a masonry outer wall and a replaceable inner wall. said outer wall including channel-shaped tile anchoring boxes afiording sill blocks and lintels, and pilasters interposed between the sill and lintel-forming portions of said anchor boxes, and said inner wall including shelf-forming blocks extended into and anchored within said anchor boxes.

8. The structure defined in claim 2 in which the sill and lintel-forming portions of said anchor boxes have engaged vertical webs that close said boxes at the outer side of the wall.

10. A wall structure made up of a masonry outer wall and a replacable inner wall, said outer wall having vertically spaced horizontally extended pockets and vertically spaced horizontally extended blocks with belts of masonry work supported on the outwardly projecting ends of said blocks, and said replaceable inner wall having shelf-forming blocks extended into the pockets of said outer wall and supporting horizontal belts of masonry work.

11. The structure defined in claim 10 in further combination with .key blocks interposed between the tops of said shelf-forming blocks and the tops of said pockets.

12. The structure defined in claim 10 in further combination with key blocks interposed between the tops of said shelf-forming blocks and the tops of said pockets, said shelf-forming blocks being positively interlocked to the bottoms of said pockets.

13. A wall structure made up of a masonry outer Wall and a replaceable inner wall, said outer wall having anchor-receiv ing pockets and said replaceable inner wall having a highrefractory molded body portion and anchor blocks anchored thereto and within the pockets of said outer wall.

14. The structure defined in claim 13 inwhich said anchors are made up of shelfforming blocks and key blocks.
